Hi, I have an unusual problem with my The Addams Family and it is now driving me insane!
I installed an off the board battery holder on my WPC CPU board, a relatively simple job. I did my other machines also. Now I am not sure that this has caused the issue or whether it was just bad timing!
When I powered the machine up, the upper left flipper (The Thing Flipper!) went slowly up held for a second and then went back down and now it does not work anymore. I have checked for power at the solenoid and there is none. There is also none at J802 terminals 1 & 3 on the Fliptronics I board, which are for the flipper. I tried to test the TIP36C transistor as best I could and it seems it is exactly the same readings as the other 3 TIP's.
I swapped the board around with my Twilight Zone Fliptronics II board and it still did not work.
I have a basic electronics understanding and am quite happy with testing circuits etc. and following wires. I cannot for the life of me find anything that the power and holding circuit have in common as I think this may be the issue.
I have checked all wiring and the EOS switch and flipper switch wiring and am now left scratching my head and hoping someone with heaps more nouse than me can help me figure out what is wrong.
Thanks in advance to anyone suggesting advice. It may take me a bit to get back to you all as I am working the weekend, but will certainly be checking with interest.
